Model “KOZAK” is made by the ZBROIA® Company since December 2014 in Kharkov, Ukraine. It is pre-charged pneumatic (PCP) air gun. It is made in semi bull pup configuration with an adjustable cheek piece that adjusts up to 15 mm. The main designing criteria of this air gun was accuracy, quality, reliability and ergonomics.
The air gun is offered in calibers 4,5 and 5,5 mm (.177’ & .22’). Also, there are two standard barrels and reservoirs of high pressure: 330 mm / 180 sm3 and 450 mm / 220 sm3. The weight of air gun is – 3,0 and 3,1 kg, the length – 710 and 805 mm, accordingly.
The ZBROIA`s barrel has a very effective integrated sound moderator. This air rifle has a build in regulator, which allows for very good shot to shot consistency.
High pressure reservoir was designed by the company specialists together with a profile Research Institute. The working pressure of the reservoir, which is shown on manometer WIKA, is 300 Bar. Each reservoir is tested to 495 bar during production.
Distinctive feature of the reservoir is built-in regulator (reducer), which operates shot to shot velocity within 1% deviation. Regulator also helps with an optimal air consumption. That is why, the full fill of the reservoir is enough for more than 100 shots in caliber 177’ or 60 shots in caliber 22’.
The reservoir is removable, it can be removed by twisting. The Picattinni / Weaver rail length is 180 mm, It is aligned with the body of air gun and allows easy installation of any optic scope.

The forward lever makes cocking very ergonomic. This allows reloading of the rifle without the need to take your eyes from the target. The adjustable trigger is made from a high strong steel. The safety mechanism prevents accidental shots. Trigger first stage length and second stage weight can be adjusted. To adjust the trigger action needs to be taken out of the stock. Some of the materials used are provided by the best European manufactures (springs, orings and gauge) Materials of metal details are from Austria.
Because of ergonomics of air gun was used model Bull Pup with a comfortable adjustable stock and pistol style handle. This configuration provides a good balance and weight. The filling port is conveniently located under the cap of manometer.
